The stair stories with greyhounds are usually pretty good. Most come from the track around 3-5 years old and have never seen a flight of stairs in their lives. Max was 3 when I got him and walked right up the stairs as soon as I got him home so I thought the stair thing wasn't going to apply to him. But, when it came time for him to walk down the stairs, he decided to do the whole flight of 14 stairs in 3 strides. I thought he'd killed himself for sure. He gave me a funny look at the bottom like, "I'm pretty sure that wasn't quite right". After he learned indoor steps, he had to learn outdoor steps, too. You know, the kind with only the steps and no risers. He'd always go up about 2 steps then try to poke his head under the next one like he was going to walk through them. Took several weeks of coaxing before he got those steps right. So, once your pup learns indoor steps, you may still need to teach him outdoor steps, too.
